The mixed woodland, ponds, streams and meadows makes it one of the best wildlife spots in the Pennines for nature watching The locals call the area 'little Switzerland' due to its Alpine style terrain and a wealth of wildlife from birds to bugs. The whole area is densely wooded especially the steep valley sides, with the landscape being characterised by deep rocky ravines, falling streams and wooded areas. Halfway up the valley are the 'Crags' which are impressive stacks of millstone grit, a 'must see' for geology lovers. Hardcastle Crags is well known as the home of the Northern Hairy Wood Ant which lives in huge anthills with nests as large as six feet tall. It also has some fine Meadows
